Lightweight game audio

Oddio

Oddio is a game-oriented audio library that is:

• Lightweight: Fast compilation, few dependencies, and a simple interface
• Sans I/O: Send output wherever you like
• Real-time: Audio output is efficient and wait-free: no glitches until you run out of CPU
• 3D: Spatialization with doppler effects and propagation delay available out of the box
• Extensible: Implement Signal for custom streaming synthesis and filtering
• Composable: Signals can be transformed without obstructing the inner Signal's controls

Example

let (mut scene_handle, scene) = oddio::split(oddio::SpatialScene::new());

// In audio callback:
let out_frames = oddio::frame_stereo(data);
oddio::run(&scene, output_sample_rate, out_frames);

// In game logic:
let frames = oddio::FramesSignal::from(oddio::Frames::from_slice(sample_rate, &frames));
let mut handle = scene_handle.control::<oddio::SpatialScene, _>()
    .play(frames, oddio::SpatialOptions { position, velocity, ..Default::default() });

// When position/velocity changes:
handle.control::<oddio::Spatial<_>, _>().set_motion(position, velocity, false);
